Abstract

An inertial instrument including a multiplexed rebalance network and an associated plurality of inertial sensors and associated position signal generators, and torquers. The rebalance network includes a sampling network, a computing network, and a conversion and distribution network. The sampling network generates a succession of digital position words representative of a corresponding succession of sampled values for the position signals. The computing network successively transforms each of the digital position signals into digital rebalance loop compensation signals for the corresponding inertial sensor. The conversion and distribution network converts the digital rebalance loop compensation signals to rebalance torquer signals and applies those signals to the respective torquers.
